PATENT BENJAMINE ATKNSON, OF SALT LAKE CITY, UTAH.

DRINKING-FOUNTAIN FOR STOCK.

Application le. April 19,

To all flu/rom i may concern.'

Be it known that I, BENJAMINE irniN- soN, a British subject, residing atSalt Lake City, county of Salt Lake, and State of Utah, have inventedcertain new and useful improvements in Drinkingdfountains for Stock; and1 do hereby declare the 'following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in drinking troughs for animals ofvarious kinds.

it is primarily intended for use in water ing poultry, but is capable ofbeing made on a larger scale for use with larger animals, such as hogs,sheep andl stock generally.

' The invention is intended to provide a cheap, simple and eilicientapparatus which can be co veniently transported from place to place, theparts of which can be conveniently cleaned when desired, and in whichthe water is supplied to the animals in a strained condition and inwhich it is in a large measure protected from the presence of foreignmatter.

The invention also includes means whereby the operative parts forsupplying the water are protected against accidental injury.

The invention will be more fully understood after reference to theaccompanying drawings, in which like parts are indicated by similarreference symbols throughout the several views, and in which Figure 1 isa sectional eleva-tion showing the main supply tank with the watertrough. and shed for same` connected thereto, and with the automaticsupply control apparatus shown in elevation.

Fig. 2 shows a section along the line 2 2 of Fig. 1, and looking down;and

Fig. 3 shows a section along the line 3 3 of Fig. 2, the' parts beingshown in elevation.

1 represents the supply receptacle which can be preferably a metal tankof either cylindrical or rectilineal shape, to which is connected,preferably by soldering, a trough 2, which trough is preferablycrescentshaped as shown in Fig. 2 so as to secure the advantage of thestrength of the arch and the avoidance in a large measure of angularcorners in which foreign matter can accumu- Specication of LettersPatent.

late; thus the trough can be more conveniently cleaned out when desired.

Projecting from th side of the tank above the trough is a delivery pipehaving the screw-threaded ends 3 projecting outward, and provided insidethe tank with an l. 4l carrying on its open mouth the wire screen 5, asshown most clearly in Fig. 3. Secured to the screw-threaded ends 3 ofthe delivery pipe is a hollow valve casing G, which is provided with atapered valve seat 6"* screwthreaded, as at 6b, to screw on the deliverypipe, and is also provided with a serewthreaded pipe i3 for purposeswhich will be hereinafter described.

A tight joint is made where the 'delivery pipe passes through the sideef the tank in any convenient way, as by means of the rubber gasket 7,metal washer 8 and the nut 9.

Fitting over the operative parts of Jthe valve mechanism there is acover 1() which protects said mechanism from accidental injury, or frombecoming clogged up from dirt, or foreign matter accumulating` on the Imay provide an inclined shed 11 ,sm-.ured to the side of the tankmounted above the trough, which will in a large measure prevent dust,leaves or the like from fallinp,- into the trough and fouling the watertherein.

ll/lounted in the top part of the valve casing is a sleeve 12 which isscrew-three ded to engage the screw threads G and is covered by thescrew-threaded cap 13.

14: represents a valve stein carrying the tapered valve 141 which i'itssnugly on the valve seat 6 when the float 15 is raised by the pressureof the water in the trough. This valve stein 14- passes freely throughthe removable guide plate 17 and is held against dropping out by a nut18, which nut and the head of the valve stem project up into the sleeve12, when the valve is lifted. The lower end of the valve stem is securedto the iioat 15 in any convenient way, by the nut 11, engaging beneaththe disk 2O attached to the float by the screws or bolts 16. This float15 may be of any suitable material, such as wood or cork, or if desireda hollow metal float may be used.

The receptacle 1 is preferably closed by a suitable cover 21 and may befilled by hand, or may be supplied with water from any suitable sourceof supply through a pipe 22 controlled by a valve 23, as indicated indotted lines in Fig. l.

The operation of the device is as follows:

If both the tank l and the trough 2 be empty, when water is poured intothe tank and rises above the screen 5 it will flow through the screenand through the delivery pipe into the valve casing 6, and past thevalve seat 6a into the trough. 1When the water has risen in the troughto a suiicient height the ioat l5 will automatically cause the valve 14ato close the passage by the valve seat, and a further influx of waterinto the trough will be arrested. As soon as the surface of the water inthe trough is suiiiciently lowered, either by evaporation, or by thedrinking of the water by the animals, the float will fall again,lowering the valve and permitting the flow of sufcient water into thetrough 2 to again lift the float and again close the valve.

The cycle of operations will continue indefinitely until the level ofthe water in the tank l has fallen too low, when the tank should bereiilled.

In order to overhaul or clean the various parts, lift oit1 the cover l0,unscrew the cap 13, take off the nut 18, then turn the valve casing 6through a sufcient angle, to permit the valve stem lll to be drawnsidewise of the trough until the valve stem is out of the casing, thenunscrew the valve casing, clean out the same, clean out the supply tank,and clean 0H the screen 5, also clean out the trough 2. To assemble theparts reverse the operation.

By having the inner orifice of the supply pipe in the 'form of an L,this pipe may be more conveniently held while the nut 9 is being set up,and when the said nut is being turned for removing the supply pipe fromthe apparatus.

It will be obvious that various modifica tions might be made in theherein described apparatus, and in the construction, combination andarrangement of parts which could be used without departing from thespirit of my invention; and I do not mean to limit the invention to suchdetails except as articularly pointed out in the claims.

aving thus described my invention what I claim and desire to secure byLetters Patent of the United States is zl. Apparatus of the characterdescribed comprising a main supply receptacle provided with a troughattached to the lower side of said receptacle exterior thereto, adelivery pipe opening from the interior of said receptacle and havingits outer end screw threaded and projecting above said trough, a hollowvalve casing screwed on the outwardly projecting end of said deliverypipe, and provided with a tapered valve seat in its bottom and with anopening in the top, a valve stem provided with a tapered portion nearits lower end forming a valve7 a removable guide plate mounted in saidcasing and engaging said valve stem, and a float attached to the lowerend of said valve stem and mounted inside said trough, substantially asdescribed.

2. Apparatus of the character described comprising a main supplyreceptacle pro vided with a trough attached to the lower side of saidreceptacle exterior thereto, a delivery pipe opening from the interionofsaid receptacle and having its outer end screw threaded and projectingabove said trough, a hollow valve casing screwed on the outwardlyprojecting end of said delivery pipe, and provided with a tapered valveseat in its bottom and with an opening in the top, a valve stem providedwith a tapered portion near its lower end forming a valve, a removableguide plate mounted in said casing and engaging said stem, a nut on theupper end of said stem above said guide plate, and a float attached tothe lower end of said valve stem and mounted inside said trough,substantially as described.
